If the process doesn’t control to the set point on your Watlow Controller: * Perform autotune or manually tune the system. * Set the control mode appropriately (Open vs Closed Loop). * Set the control set point in the appropriate control mode and check the source of the set point: remote, idle, profile, closed loop, open loop.
What does Alarm Error 1 Alarm Error 2 Alarm Error 3 Alarm Error 4 mean on my Watlow Controller?
If your Watlow Controller displays 'Alarm Error 1 Alarm Error 2 Alarm Error 3 Alarm Error 4', it could be due to a sensor issue or calibration problems. Try the following: * Correct the wiring or replace the sensor if it's improperly wired or open. * Match the controller setting to the sensor used. * Check the calibration of the controller.
Why is the temperature runaway on my Watlow PM PLUS 6?
If the Watlow Controller's temperature is running away, take these steps: * Verify the output function is correct (heat or cool). * Correct the sensor wiring (red wire negative). * Verify and correct all wiring. * Replace the heater. * Replace or repair the power controller. * Replace or repair the controller.
What to do if Watlow PM PLUS 6 displays Error Input [1,2]?
If your Watlow Controller displays 'Error Input [1,2]', it indicates that there is no valid signal to the device, or the sensor may be improperly wired or open. To fix this: * Correct the wiring or replace the sensor. * Match the setting to the sensor used. * Check the calibration of the controller.
How to reset an alarm on a Watlow PM PLUS 6 Controller that won’t clear?
If your Watlow Controller's alarm won’t clear or reset, try the following: * Reset the alarm when the process is within range, or disable latching. * Set the output to the correct alarm source instance. * Set the alarm source to the correct input instance. * Correct the cause of the sensor input being out of the alarm range. * Set the alarm set point to the correct trip point. * Set the alarm to the correct type: process, deviation, or power. * Set the digital input function and source instance.
What to do if my Watlow PM PLUS 6 has no heat or cool action?
To address a 'No heat/cool action' issue on your Watlow Controller: * Ensure the output function is correctly set. * Set the control mode appropriately (Open vs Closed Loop). * Correct the output wiring. * Resolve any faults in the system, such as an open load, power issue, or blown fuse. * Set the control set point in the appropriate control mode and check the source of the set point: remote, idle, profile, closed loop, open loop. * Obtain the correct controller model for your application.
How to fix a Watlow Controller with no display?
To resolve a 'No Display' issue on your Watlow Controller: * Ensure the controller is powered on. * Replace any blown fuses. * Reset tripped breakers. * Confirm the safety interlock switch is closed. * Reset the limit, correct any wiring errors, and apply the correct voltage, verifying the part number.
What does Limit Error mean on my Watlow PM PLUS 6 Controller?
If your Watlow Controller displays 'Limit Error', it indicates a sensor issue or calibration problem. To resolve this: * Correct the wiring or replace the sensor if it's improperly wired or open. * Match the setting to the sensor used. * Check the calibration of the controller.
